Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 1558.79 g/mol gives Peptide 74 (H-8545.0500) distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Peptide 74 (H-8545.0500) (CAS 132116-39-3), a certified reference material (molecular formula C62H107N23O20S2, MW 1558.79 g/mol) for analytical method development and quality control.
Peptide 74 (H-8545.0500) (C62H107N23O20S2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
